Jason, my apologies for the late reply!
We have regular meetups every month. The first Thursday at 6pm. We're always looking for new members and possible meetup sponsors. We also organize hacker-maker events and are in the process of advocating for open data at the public/policy level.
I'd be happy to talk to you further about this, or if you'd like to come to our March Meetup, we'll be showcasing the things we built during the International Open Data Data Hackathon this past weekend.
